Rapper XXXTentacion was fatally shot on Monday as he was leaving a motorcycle dealership north of Fort Lauderdale, Florida, TMZ reports.

The Broward County Sheriff’s Office told PEOPLE that authorities could not confirm XXXTentacion (born Jahseh Onfroy) was the victim but that they had responded to a shooting at a Deerfield Beach motorsports dealer.

The shooting was first reported at 3:57 p.m., according to the sheriff’s office.

Sheriff’s officials said later Monday afternoon that the victim in that altercation had died after being hospitalized. The victim was described as an adult male but further information was not immediately released.

A witness said someone in a black Dodge SUV fired on someone in a black BMW, according to the dispatcher.

An apparent onlooker at the scene soon shared video on Twitter that was widely viewed showing a man who looks like XXXTentacion sitting motionless in the front seat of a vehicle as someone checked his pulse.
